Hey guys, in case you have more general questions about code instrumentation and OpenTelemetry, you'll probably find answers in this video: th-cam.com/video/ICCspGTRTXw/w-d-xo.html

Great video, However I have some json data which will be sent to Otel [ which acts as a middle man] Im looking for a way to convert json data into otel acceptable format of metrics . Is there any video for the same ?

[@AlienAndrew51]

Is there a way to connect services as an entire trace or is that what is happening here? I'm just not understanding how Open Telemetry can connect multiple services together, I'm assuming through the trace id? Also, I'm looking into using trace tests at my company and want to test through the entire application. It would be great if you could demonstrate how to connect multiple java container apps as one trace with trace test. I've seen your other videos, but I'm still learning the SRE side of things as a Software Engineer.

[@isitobservable]

Hi Andrew,
you should be able to do so by using the auto instrumentation agent of Java. each of you java service will produce spans...and you will get traces that you could use with tracetest.

[@AlienAndrew51]

​@@isitobservableObservable Thanks for the reply! I will give it a go when I get a chance to set up a POC.

Is it mandatory that we use only java application for OpenTelemetry in java? I hava a c++ code which I want to use, can I use OpenTelemetry Java for it?

[@isitobservable]

Hi , every language needs to use its own OpenTelemetry sdk and instrumentation library. In my case i showed how to instrument the java code using the java library. In your case ( c++), you will need to use the following library :github.com/open-telemetry/opentelemetry-cpp

When I ran the help install prometheus command I see this : Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(Deployment.spec.template.spec.nodeSelector.selector): invalid type for io.k8s.api.core.v1.PodSpec.nodeSelector: got "map", expected "string"

[@isitobservable]

Hi i have updated the readme file (and remove the node selector). Thanks for the feedback.

[@rhmoult]

I am not interested in using Kubernetes. Can you point me to a tutorial that shows me how to add the simplest possible tracing to a React application? This "toy" example is way overkill and introduces too much complexity for my use case.

[@HemanthYTP]

In your git repo deploy.yaml is missing. In reference to this command in readme : "kubectl apply -f nginx/deploy.yaml"

[@isitobservable]

Hi, Thanks for the feedback. I have updaded the readme file. i'm using now the lates helm chart of nginx

Content is great, sound quality is so-so... Maybe buy a better mic and this will be a top tier youtube channel!

[@isitobservable]

Noted!

[@johnmorsley]

I cannot watch because of the mind numbingly distracting and annoying background music (noise)! :(

[@isitobservable]

Noted . Unfortunately not able to remove it on this content. but i will reduce the volume of the background music. Thanks for the feedback.

[@FunkyMacky]

@@isitobservable i liked the music :D
